In order to make the EU server feel better after the American marathon, Wargaming.net has prepared something special for a handful of people from the RU server who will buy VIP tickets for WG Fest 2017. Each of these players will receive a bonus code that will give the option to choose one of four Wargaming games in order to get a special reward.
The ones who choose the WoT reward will get the M4A2 Sherman Loza.
According to the official RU portal announcement, the tank will receive an unique commander and will not be available for sale anywhere else. Hopefully we can expect the tank in the future either in our premium stores or in the form of reward for some type of marathon (either in the Advent Calendar).
